“…The SGXR, located in the western Songliao block [6,25,26] ( Figure 1B), is characterized by widespread Late Paleozoic to Mesozoic volcanic-sedimentary successions ( Figure 1C), and a number of world-class Pb-Zn-Ag-Cu-Mo polymetallic deposits are hosted in these successions (e.g., the Bairendaba, Huanggangliang, Bianjiadayuan, Dajing, and Haobugao deposits) [27][28][29]. The NE-trending Huanggang-Ganzhuermiao and EW-trending Xilamulun faults dominate this region and control the emplacement of the intrusions and the distributions of the polymetallic deposits [28][29][30] ( Figure 1C). Moreover, intense magmatic events have been identified in this region, which has broadly distributed I-and A-type granitoids [5,6,21].…”

“…On the basis of a precise framework, these granitoids were considered to be emplaced in two geotectonic stages. The first group includes granodiorite, diorite, and tonalite with ages ranging from 321 to 237 Ma, which originated in the mantle and recycled ancient crustal materials, where the magmatism was associated with the closure of the Paleo-Asian Ocean, post-orogenic extension, and plate subduction [5,[30][31][32][33]. The second group consists of monzogranite, syenogranite, and granodiorite with ages ranging from 150 to 131 Ma, which were derived from lower crustal materials, where the magmatism was related to plate subduction, lithospheric delamination, and extension [5,10,34,35].…”

Petrogenesis and Tectonic Setting of Ore-Associated Intrusive Rocks in the Baiyinnuoer Zn–Pb Deposit, Southern Great Xing’an Range (NE China): Constraints from Zircon U–Pb Dating, Geochemistry, and Sr–Nd–Pb Isotopes

et al. 2019

The Baiyinnuoer skarn Zn–Pb deposit, located in the Southern Great Xing’an Range, Northeast China, is the largest Zn–Pb deposit of the northern China, with a total reserve of 32.74 Mt at average grades of 5.44% Zn and 2.02% Pb. The Zn–Pb ore bodies are hosted in the Lower Permian Huanggangliang Formation. The results of zircon U–Pb geochronology show that the ore-associated granodiorite porphyry, granodiorite, and diorite were emplaced at 248 ± 1.3, 251 ± 1.8, and 249 ± 1.4 Ma, respectively. The granodiorites and granodiorite porphyry have low P2O5 (0.13–0.23 wt %) and A/CNK (0.79–1.05) values, and their SiO2 and P2O5 contents are negatively correlated, indicating I-type affinity. The positive εNd(t) values (+1.3 to +1.8) and young two-stage model ages (TDM2) (880–916 Ma) of the Baiyinnuoer intrusive rocks suggest that they might have formed by the mixing of both mantle and crustal materials. The variations in the major elements, Rb, Sr, and Ba, and the negative Nb–Ta–Ti anomalies indicate that fractional crystallization might have occurred during magma ascent. In combination with the regional geology, the new geochronological, geochemical, and isotopic data reveal that the ore-associated intrusive rocks at Baiyinnuoer were formed in a post-collision setting in the Late Permian.

The Southern Great Xing'an Range (SGXR) hosts a number of Early Cretaceous Sn and associated metal deposits, which can be divided into three principal types according to their geological characteristics: skarn type deposits, porphyry type deposits and hydrothermal vein type deposits. Fluid inclusion assemblages of different types of deposits are quite different, which represent the complexities of metallogenic process and formation mechanism. CH4 and CO2 have been detected in fluid inclusions from some of deposits, indicating that the ore‐forming fluids are affected by materials of Permian strata. Hydrogen and oxygen isotope data from ore minerals and associated gangue minerals indicate that the initial ore fluids were dominated by magmatic waters, some of which had clearly exchanged oxygen with wall rocks during their passage through the strata. The narrow range for the δ34S values presumably reflects the corresponding uniformity of the ore forming fluids, and these δ34S values have been interpreted to reflect magmatic sources for the sulfur. The comparation between lead isotope ratios of ore minerals and different geological units’ also reveals that deeply seated magma has been a significant source of lead in the ores.

“…The superposition and transformation of different tectonic systems has made the region a key area for understanding the tectonic evolution of Northeast Asia, especially in the Mesozoic. In addition, the Great Xing'an Range is also considered to be one of the most important metallogenic belts in China, and the relationship between Mesozoic magmatism and mineralization has become a hot issue in recent years (Li et al, 2014;Wang Y H et al, 2015;Gao et al, 2017;Wang et al, 2018;Zhou Y T et al, 2018;Deng and Li, 2019;Ma et al, 2019). Therefore, it has a very important scientific and practical significance for the research on magmatic events in this area.…”

A large amount of igneous rocks in NE China formed in an extensional setting during Late Mesozoic. However, there is still controversy about how the Mongol-Okhotsk Ocean and the Paleo-Pacific Ocean effected the lithosphere in NE China. In this paper, we carried out a comprehensive study for andesites from the Keyihe area using LA-ICP-MS zircon U-Pb dating and geochemical and Hf isotopic analysis to investigate the petrogenesis and tectonic setting of these andesites. The U-Pb dating yields an Early Cretaceous crystallization age of 128.3±0.4 Ma. Geochemically, the andesites contain high Sr (686-930 ppm) and HREE contents, low Y (11.9-19.8 ppm) and Yb (1.08-1.52 ppm) contents, and they therefore have high Sr/Y (42-63) and La/Yb (24-36) ratios, showing the characteristics of adakitic rocks. Moreover, they exhibit high K 2 O/Na 2 O ratios (0.57-0.81), low MgO contents (0.77-3.06 wt%), low Mg # value (17-49) and negative ε Hf (t) values (−1.7 to −8.5) with no negative Eu anomalies, indicating that they are not related to the oceanic plate subduction. Based on the geochemical and isotopic data provided in this paper and regional geological data, it can be concluded that the Keyihe adakitic rocks were affected by the Mongol-Okhotsk tectonic regime, forming in a transition setting from crustal thickening to regional extension thinning. They were derived from the partial melting of the thickened lower crust. The closure of the Mongol-Okhotsk Ocean may finish in early Early Cretaceous, followed by the collisional orogenic process. The southern part region of its suture belt was in a post-orogenic extensional setting in the late Early Cretaceous.
